About overcurrent protection and selecting external diode

Question asked by Tarzan on Mar 7, 2014

Hi ,

I have some questions about LDO products.

 

#1,

It looks like that ADI LDO products have current limitting protection, not current foldback.

I just wondered why most LDO's current protection is current limitting.

 

#2,

Now I'm condering to use ADP121.

Do you think it's better to use an external diode between Vin and Vout?

The datasheet does not mention to use external diode to prevent from over current flow  in case of Vout>Vin.

 

Thanks in advance

 

Best regards,

Tarzan
